TO ALL WHOM IT MAY CONCERN:

'Be it known that I, HORACE A. ROBISON, of Cleveland, vcounty of Cuyahoga, in Athe State of Ohio, have invented a new and improved Mode of Constructing Weather-Strips for bottom of doors, to exclude air, dust, rain, or'snow; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, andY to theletters of reference marked thereon.

Figure 1 is a perspective view, showing weather-strip in place.

Figure 2 is a vertical section of door, representing the construction and application of said strip.

The nature of myinvention consists in so constructing the weather-strip as to effectually exclude the passage of air, dust, rain, or snow.

The diiculty heretofore has been, in all other strips intended for this use, that there has been an opening where said strip swung in its attachment to the door. Now, this I have completely obviated by making a double weather-strip or substituting a piece of rubber in place of hinges, which extends the whole length,and by its 'elasticity serves the double purpose of hinge and protection. i v

So that others may understand the construction and operation of my i1nprovement, I will proceed to describe it. v

A represents a door, to which is firmly attached the upper half of my weather-strip B. This I make in any desired pattern of moulding, the under side of`whieh is made concave, and projects beyond or is thicker than the under or swinging piece C, so that water will fall outside. The under side of the piece B and the upper side of piece C have a slot or groove, a b, into which is guvmmed and nailed a strip of rubber, c, which7 allows, by its elasticity,v the piece C to swing as on a hinge and adjust itself in place. The piece C also Ahas a piece of rubber, g, gummed and nailed into a slot in the lower side of it, which, when the door is closed, is pressed down on to the threshold, and prevents the admission ofair, dust, or Water, and by its elasticity will adjust itself to any inequalities which may arise by wearing away of said threshold. Near each end of the pice B is a cavity, E, into which` is sprung a piece of rubber,f, that, when the door is opened, forces the swing-piece C away and permits the door to swing freely. On each' side ofthe door-frame I place a small stop,l of wood or other suitable material, K, against which the ends of the piece C strike and close it down, when the space under the door is entirely closed, and no wind, dust, rain, or snow, .can pass. The strip may be secured to the door by means of screws S or otherwise.

I claim the combination of the strips B and C, united by the rubber strip c running the entire length of the strips B and C, the springvand the rubber strip g, all constructed in the manner as and for the purpose sot forth. t
